Hey, no problem! I remember paying around €560.00 to replace my glow plug. It was a bit expensive, but it solved the problem due to wear and tear. Since the mechanic visit, my car has been running perfectly again and I haven't noticed any other problems that could be related to it. It was definitely the right decision to have the replacement done. Hope this helps you!

Cylinder 4 glow plug control circuit any ideas what the fix is for this ?
The error code for Cylinder 4 Glow Plug Control Circuit usually indicates a problem with the glow plug itself or the wiring to it. Start by inspecting the glow plug and its connection. If the glow plug is faulty, it will need to be replaced. If the wiring is damaged, it will need to be repaired. If you're not comfortable doing this yourself, I recommend taking your car to a professional mechanic.

You can certainly just replace the faulty glow plug. However, if the others are old or showing signs of wear, it might be a good idea to replace them all at once to prevent future issues.

Hey, I actually had a similar problem with my diesel Opel Vectra from 2003. My glow plug was also defective and I had similar symptoms to yours, such as the constantly illuminated preheating light and problems with cold starts. As I know a lot about cars, I took the risk of fixing the problem myself. It turned out that the glow plug could no longer do its job due to wear and tear. In my case, I had to replace the faulty glow plug. And yes, it is a serious problem because it affects the performance of the engine. So, my advice is to find a trustworthy mechanic as soon as possible and get the glow plug(s) checked/replaced. Hopefully my experience will help you. Good luck with it!
